课程名称：喂养世界 课程概述： 《喂养世界》课程将探讨当前食品生产科学背后的重要概念，包括人口增长、城市化、逐渐富裕、资源限制及生物学上的基本限制，主要聚焦于牲畜生产。课程将涵盖主要的食品动物种类（乳制品、猪肉、牛肉和禽肉），讨论它们的普遍生命周期、生产限制以及新兴的社会问题。 在课程中，我们将探讨一些重要而艰难的问题： - 动物产品的生产和消费对健康的主要好处和潜在关注点是什么？ - 动物生产如何影响资源的有效利用并对环境造成影响？ - 如何降低生产成本以满足全球对动物产品日益增长的需求，同时保障动物和消费者的健康与安全？ - 存在何种类型的动物食品生产系统？ 我们还将讨论围绕动物食品系统的神话和误解，并密切关注科学家、农民和兽医通过合作所努力解决的一些全球性问题、挑战与困境。 本课程的讲座将由宾夕法尼亚大学兽医学院的几位专家主讲，他们在动物生产系统的研究和推进方面有着深入的参与。该课程适合希望深入了解动物食品系统的学习者，以及那些可能从未参观过动物农场但渴望了解我们食品来源及可持续性问题的人。 课程大纲： 1. **人口增长与全球动物产业** 介绍全球食品安全的紧迫需求，讨论相关挑战和伦理问题，并回顾动物在食品生产系统中的角色及生产趋势。 2. **动物生产相关问题** 探讨动物生产操作的基本原则及相关问题，包括食品系统的效率、环境影响及动物福利关注点，同时讨论水作为食品生产系统的重要资源。 3. **动物饲料与环境** 重点关注动物饲料在动物生产系统中的重要角色，了解饲料成分及分类，探讨营养素如何在环境中流动，并识别食品浪费问题及解决方案。 4. **一般动物生产、效率与食品安全** 讨论影响农场动物产量及环境效率的因素，探讨食品安全和抗生素在食品生产中的使用，强调兽医在牲畜系统中的重要性，并讨论发展中国家的食品安全与养殖挑战。 5. **乳制品生产** 探索乳业生产领域，包括乳牛的生命周期及乳制品生产的环境影响，涉及住房系统、挤奶技术、趋势及动物福利问题，并讨论美国乳制品生产中的公共卫生关注点。 6. **猪肉生产** 分析美国养猪系统中市场猪和母猪的生命周期，了解猪舍的设计及其背后的理念，以及当前影响猪肉产业的趋势和挑战。 7. **禽肉生产** 考察美国禽肉的生产系统与生命周期，关注动物福利问题及新兴挑战，并讨论与禽肉生产系统相关的公共卫生问题。 8. **牛肉生产** 课程的最后一个模块重点关注牛肉生产系统，分析美国肉牛的生产系统与生命周期，讨论动物健康及公共卫生问题，最后讨论国际牛肉产业。
Name:Population Growth and Global Animal Industries
Description:This module introduces the course by discussing the pressing need to address global food security as well as the accompanying challenges and ethical issues. We also explore the role that livestock play in the food production system and review trends in animal production.
Name:Issues Surrounding Animal Production
Description:This module begins to explore the fundamental principles of animal production operations and the issues surrounding animal production. We will look at the efficiency and environmental impact of the food system as well as animal welfare concerns. Finally, we will discuss the importance of water as an essential resource for the food production system.
Name:Animal Feeds and the Environment
Description:This module focuses on animal feeds and their important role in the animal production system. You will gain an understanding of the constituents in feed as well as how feed is classified. We will also examine and explain how nutrients flow through the environment. Finally, we will look at the problem of food waste and identify solutions.
Name:General Animal Production, Efficiency and Food Safety
Description:This module continues the discussion of animal production operations by looking at factors that affect farms’ animal yields and environmental efficiency. We will also explore food safety, how and why antibiotics are used in food production, and the importance of veterinary medicine as part of the livestock system. Finally, we will look at the challenges of food security and livestock farming in the developing world.
Name:Dairy Production
Description:Welcome to the first week of the course which explores a particular animal production sector. The focus for this module will be dairy. The life cycle of a dairy cow as well as the environmental impact of dairy production will be covered. We'll also explore housing systems, milking technologies, trends and animal welfare issues in the dairy production system. Finally we will address public health concerns in dairy production including hormone use, antibiotic use, and milk safety in the U.S.
Name:Swine Production
Description:This module will examine the life cycle of market hogs and mother sows in the U.S. swine production system. Swine housing and the rationale behind those facilities will be covered in addition to welfare and the trends and challenges currently affecting the swine industry.
Name:Poultry Production
Description:This module examines the production system and life cycle of U.S. poultry. We'll address animal welfare issues and emerging challenges and finish the week with a discussion about public health concerns related to the poultry production system.
Name:Beef Production
Description:The final module of the course focuses on beef production systems. We will examine the production system and life cycle of U.S. beef cattle. Then, we'll address animal health as well as public health issues. Finally, we'll finish the week with a discussion about the international beef industry.
This course will explore the concepts driving current food production science (population growth, urbanization, emerging affluence, resource constraints, and underlying biological limits) with the main focus on livestock production. Each of the major food animal species (dairy, swine, beef, and poultry) will be covered in terms of their universal life cycles, constraints to production and emerging societal issues. Throughout the course, we will tackle some difficult and important questions: What are the major health benefits and potential concerns regarding the production and consumption of animal products? How does animal production affect the efficient use of resources and impact our environment? Can cost of production be reduced to meet growing demand for animal products around the globe while maintaining health and safety for both animals and consumers? What are the different types of animal food production systems? Myths and misconceptions surrounding the animal food systems will be discussed. We’ll also look closely at some of the global issues, problems, and challenges in these food systems which scientists, farmers, and veterinarians, are attempting to solve through collaboration. Lectures will be delivered by several experts from the University of Pennsylvania, School of Veterinary Medicine who are intimately involved in the study and advancement of animal production systems. The course is geared towards learners who seek a greater understanding of animal food systems as well as those who might have never visited an animal farm, but have a desire to learn more about where some of our food comes from and issues surrounding sustainability.
